The case is deadly serious, but the mood in U.S. District Judge Reggie Walton’s courtroom has been light at times during the jury-selection process in the perjury retrial of Roger Clemens.

Prosecutors, defense attorneys and the judge hearing the baseball pitcher’s retrial in Washington seemed to be in good spirits this evening at the conclusion of the second day of jury selection, chuckling at some offbeat remarks made by potential jurors and both sides in the case.

A female juror left almost everyone in the courtroom gleefully laughing after she exchanged remarks with Walton after he asked her what position her grandson plays at the University of Virginia’s football team.

“Grandmas are not supposed to know that,” the woman told Walton. (She’s part of an organization that advocates for Washington’s statehood.)

Her grandson’s football career was mentioned a second time during questioning, to which she responded: “As a grandmother, I would prefer him not to play football because he could get hurt.”

Another potential juror, a chatty lawyer and former media executive, told Clemens’ lead attorney Rusty Hardin that she “wouldn’t be the quiet type” during jury deliberation.

“I have no doubt,” Hardin immediately replied.

She exited the courtroom giggling.

The same juror also said sports are “a national treasure of the American public.” She added Congress should look into sports within its oversight capacity if there is “some serious wrongdoing” happening, particularly because children and other people “look up” to those involved in sports.

Thirty-two potential jurors have been interviewed during the first two of a possible four days of jury selection. Of those, Walton asked 15 — 11 women and 4 men — to return later this week for further questioning. Twelve jurors and four alternates will make up the jury for Clemens’ retrial.

At least four potential jurors were excused for religious reasons, including one man who said his religion prohibited him from sitting in judgment of others. Additional people were dismissed for saying that they believe Clemens had used drugs during his storied 24-year baseball career, which included a stop in Houston.

Prosecutors are accusing the baseball legend of lying to Congress about the use of performance-enhacing drugs. This is the prosecutors’ second chance to try Clemens. His first trial abruptly ended last summer when the prosecution introduced previously barred evidence and Walton declared a mistrial.

On Monday, Walton expressed his hopes to complete jury selection by Thursday. Yet, on Tuesday he complained multiple times about the slow pace of the process.

The high-profile trial, which may bring to court former baseball sluggers Barry Bonds and Jose Canseco as witnesses, could last up to six weeks. Several potential jurors expressed opinions about Bonds’ own criminal perjury case, which resulted in a conviction last year.
